Effect of a simulated engine jet blowing above an arrow wing at Mach 2.0 [PDF]

open access: yes
The effects of a gas jet simulating a turbojet engine exhaust blowing above a cambered and twisted arrow wing were investigated. Tests were conducted in the Langley 4-foot supersonic pressure tunnel at a Mach number of 2.0.

A multifaceted interplay between hemophagocytosis, IL‐18 and type I IFN distinguishes Still disease from other autoinflammatory diseases

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives The unknown pathophysiology and the lack of specific features for systemic Juvenile Idiopathic arthritis and adult‐onset Still disease (collectively Still disease/SD) delays diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory diseases ...

Flow visualization of discrete hole film cooling for gas turbine applications [PDF]

open access: yes
Film injection from discrete holes in a three row staggered array with 5-diameter spacing is studied. The boundary layer thickness-to-hole diameter ratio and Reynolds number are typical of gas turbine film cooling applications.

Augmentation of Fighter-Aircraft Performance by Spanwise Blowing over the Wing Leading Edge [PDF]

open access: yes
Spanwise blowing over the wing and canard of a 1:35 model of a close-coupled-canard fighter airplane configuration (similar to the Kfir-C2) was investigated experimentally in low-speed flow.

Comparison of aerodynamic theory and experiment for jet-flap wings [PDF]

open access: yes
Aerodynamic theory predictions made for a jet flapped wing were compared with experimental data obtained in a fairly extensive series of tests in the Langley V/STOL tunnel. The tests were made on a straight, rectangular wing and investigated two types of

Wind tunnel studies of circulation control elliptical airfoils [PDF]

open access: yes
Effects of blown jets on the lift and drag of cambered elliptical airfoils are described. Performance changes due to a splitter plate attached to the lower surface of an elliptical airfoil near the trailing edge with and without blowing are indicated ...
